>1) Why did Barr appoint Durham in October 2020 when Sessions had already appointed him?
Oct was when it was announced. No leaks.
Durham started April 17. Includes investigating the Mueller Special Counsel team.
Investigation has now been expanded to include the run up to Nov 16 election.
Sidney Powells filing in Flynn case showed Durham started in April 17.
In fact, the Strzok/Page texts prove that.
